OF BETTENDGRF, IGWA, A CORPORATION OF IOWA V RAILWAY TRUCK Original application filed June 10, 1926, Serial No. 114,987, nowlatent No. 1,787,772, dated .Tanuary'G,

-This invention relates to railwav trucks and is a division of my application, Ser; No. 114,987, filed June 10, 1926, issued January 6, 1931, as Patent No. 1,787 ,772.

An. object of the invention is to. provide improvements in so-called lateral motion trucks, consisting, broadly, in so arranging the columns of the side frames that the guide faces thereof will be spaced apart equally throughout their extent to provide space for a lengthening spring group and a full width bolster, together with guide elements for the bolster arranged in offset relation with respect to the side frames and out of line of the movement of the individual springs of the spring group.

Another object of the invention is to provide a lateral motion truck having guide means whichnot only maintain the bolster within the desired limits of movement but also serve to provide retaining guides for the roller seat during the necessary move ments of the latter.

Other and further objects of the inven tion will more clearly appear from the description and claims hereinafter following.

In the drawing, Figure 1 is a fragmentary, composite, horizontal, sectional and top plan view of one side of a truck em bodying my improvement-s. Figure 2 is a fragmentary, side elevational View of one side of saidtruck. And Figure 3 is a frag mentary, vertical, sectional view of the invention corresponding substantially to line 3-3 of Figure 2. V 7

As shown in the drawing, only one side frame and the parts associated therewith are shown, but it will be understood-that the opposite side of the truck is of a similar type. The sideframes in the truck contemplated by my invention each comprises a compression member 10, a tension member 11, journal boxes 12, and a spring. seat 13, all preferably integrally formed. The

guide columns of the side frame are indi-- cated at 1414, being preferably channelshapedv in cross-section and preferably formed integrally with the remainder of the truck. The guide columns 1414: have their bolster guide faces 15-15 disposed parallel Divided and this application filed. May 9,- 1929.

throughout their full lengths, as best shown" in Figure'2 and the distance between said guide faces corresponds with the length of the spring seat 1?). spring seat 13 and occupying the full space between the guidefaces'1515 of the guide columns are the coil springs 16, preferably in a group of six, with the end springs disposed close to the guide faces 15-15 "of the columns, the required movement of the springs, of course, being permitted by the parallel spacing of the guide faces .15 -15' which are unobstructed throughout their extents. V

Bearing upon the springs 16is a roller seat 17 formed for the reception of the upper ends of thesprings and having on its upper surface a plurality of roller seats 1818 adapted to accommodate a series of cylindrical rollers 19 l9, which are maintained in position in the roller seat member by side flanges indicated at 20. The edges 2121 of the roller seat bear upon the guide faces 15-15 of the columns during certain movement of the parts. v

A bolster 22 is width at each end adapted to slidably fit between the guide faces 1515 of the guidecolumns, the under-surface of theend ofthe bolster being provided with depressed roller seats 23-23 adapted to accommodate and bear upon the rollers 1919, as best shown in Figure 3.

. In order to restrict the movement of the bolster with reference to the side frames ofthe truck, laterally offset guides are pro Disposed upon the provided, which is of vided, each comprising a laterally extended web 24L terminating at its inner extremity'in an angularly, disposed flange 25,0ne of the guide'fianges being disposed adjacent each side of the bolster receiving opening in the side frame. Each guide extends from a point adjacent the under-surface of the compression member downwardly to a point be, low the upper ends of the spring coils 16, as indicated at 26, when said coils are in normal position. The guide flanges 2525 are out of line and to one side of the springs so that they do not interfere with thenormal movement of the 'latter and are so diss posed with reference to each other and to the guide surfaces 15 of the guide columns as to provide less space between their inner surfaces than that which is afiorded between the guide faces 15--15, and are arranged ata point where there is no interference with the utilization of the full extentof the bolster receiving opening in the side frame for accommodating the springs, roller seat and bolster. The guides at their upper ends may merge with the brake hanger brackets 27 and by reason of the fact that; the; guides extend inwardly of the guide faces of the columns, there is no necessity for spacing the hanger brackets more widely apart than in ordinary practice, thus providing an important advantage in that there is no interference with the required movement of the brake hangers.

The bolster 22 is' provided with a recess 28 in each of its side faces, each recess being defined by an end wall 29 provided by the lug 80 and by a wall 31 spaced from thewall 29 a distance to permit the required movementof the bolster longitudinally of itself, the walls 29 and 31 forming abutments to limit movement of said bolster. Due to the fact-that the guide means are positioned inwardly of the side frame, the bolster is restricted in width only at the point of engagement with the guide means, and presents its full width between the guide faces '1515 to enable the side faces of the bolster to cooperate with the guide faces 15'-15 ina normal manner. The abutment walls 29 and 31 restrict longitudinal movement of the bolster in both directions, as will be appreciated.

The roller seat 17 is of such width as to extend beyond the faces 15-15 of theguide columns, and beyond the guide flanges 25 25 and is provided with notches indicate-d at 32, each of which isadapted to slidably receive one of the guide flanges 25, these notches providing abutments which prevent movement of the roller seat transversely of the side frame, while permitting the required vertical movement incident to operation of the springs. Due to the offset relation of the guide flanges, while they maintain the desired position of the parts, they offer no interference with the desired length of the roller seat which will permit rubbing engagement of the ends thereof with the guide faces 15-l5, and are out of the way of'the required movement of the springs.

During operation, the side faces ofthe bolster and of the roller seat bear generally upon the guide faces 15-15 while these members are held within the required limits of movement by the guide ribs, at the same time being offset with respect to the side frame in such manner as to prevent interference with the movement of the springs and also afi'ord opportunity for utilization of alarge spring group and a full width bolster. 1

In assembling the truck, the end of the bolster is inserted in the window opening of the side frame before the springs are in position and the flanges 2525 engaged with the guides in the side of the bolster, the bolster then'being elevated to its proper position. The roller seat is then placed in position with the notches 32 accommodating the guide ribs 25, with the rollers 19 between the end of the bolster and the spring seat. The spring plank (not'shown) is then placed in position and the springs finally arranged within the space between the guide columns in position to support the'roller seat and bolster. V
